Transcript for Prince Harry on Baby George: Will 'Make Sure He Has Fun'

It is. Now to prince george. He has met uncle harry. And there doesn't seem to be any hard feelings of being knocked down the line of royal succession on his part. And amy robach was there for the show. Reporter: Prince harry, stepping up for the first time since spending a little quality time with william, kate and baby prince george. Fantastic to have another addition to the family. I only hope my brother knows my expense for baby sitting. Reporter: Getting a first glimpse of the family at home. About that tall, that wide. Crying his eyes out as babies do, I suppose. Reporter: Giving his view on his new nephew's life. I'll make sure he has fun. The rest of it, I leave to the parents. Reporter: The prince appearing at this support, to support his charity, an exhibit exhibition showcasing never-before-seen images of harry in private. While kate and william are getting to know their little boy, george, welcome news overnight. The french editor who published the tapless photos of kate last september when william and kate were in asia, will formally be charged for a breach of chance's strict photography laws. The photographer who took the photos will also be charged. This comes as a huge relief to william who is so protective of kate. On a happier note, robin, it was so great to see prince harry beaming last night about his new nephew, prince george. And I love the part when he said, he was going to teach him how to have fun because if anyone can, we all know harry can.
